SPECIFICATION forming part of Letters Patent No. 744,365, dated November17, 1903. Application filed December 13, 1902. Serial No. 135,130. (Nomodel.)

To all whom it may concern.-

Be it known that I, WILLIAM D. LABADIE, a citizen of the United States,residing at South'Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and usefullmprovementsin Injectors orEjectors; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in injectors or ejectors.

The object of the invention is to provide an injector or ejector ofsimple and inexpensive construction wherein the parts are detachably andadjustably connected to permit the same to be taken apart and cleanedand the ejecting tube and nozzle adjusted to regu late the quantity ofwater ejected without changing the pressure of the steam.

With these and other objects in view the invention consists in the novelconstruction, combination, and arrangement of parts, all as will be morefully described hereinafter, and

finally pointed out in the appended claims.

The invention is illustrated by a view in longitudinal vertical section.

Referring to the drawing in detail, 1 designates a cylindrical chamberor easing into which the water is admitted from a suitable water-supplyand to which it is connected by a coupling 2. The lower end of thecasing is interiorly screw-threaded to receive the threaded flange 3 ofa cap 4,which is provided with an integral steam-injecting nozzle5,projecting into the casing, and an integral coupling-head 6,projecting from the end thereof and adapted for connection with asuitable steam-supply. The upper end of the casing is exteriorlyscrew-threaded to receive the threaded flange of a cap 7, having anintegral contracted dependingwall 8, provided with apertures 9 for theadmission of the water to the cap. This depending wall serves as asupport for the ejecting-tube 10, which is screwed into the threadedopening therein, so that when the cap 7 is removed the tube 10, which isin alinement with the nozzle 5, may be adjusted nearer to or fartherfrom the nozzle to regulate the quantity of water to be ejected from thechamber 1.

On the upper end of the cap 7 is adjustably mounted, preferably byscrew-threads, an ejecting-nozzle 11. A jam-nut 12 is fitted on thenozzle and adapted to engage the outer end of the boss 13 to hold thenozzle in its adjusted position.

It will be seen that the caps at and 7 may be readily removed to cleanthe interior of the casing as Well as to adjust the tube 10 and nozzle11 relatively to each other and to the stationary nozzle 5, and thenozzle 11 and tube 10 may be moved into engagement with each other toform a continuous tube, in which case the quantity of water ejected fromthe casing is decreased without changing the pressure of steam. When,however, the tube and nozzle are separated, as shown in the drawing, thewater enters the tube and noz zle at the lower ends thereof and isejected from the chamber by the steam and injected into the pipe 14.,secured at one end to the boss 13 and which is adapted to be connectedwith-a boiler at its other end.

Having thus described my invention,what I claim, and desire to secure byLetters Patent, is

' 1. In an ejector, a casing, a removable cap to close one end of thecasing, a steam-injecting nozzle on the cap, a removable cap to closethe other end of the casing, an ejecting-tube carried by the cap, anejecting-nozzle carried by the cap, and means to permit the nozzle andtube carried by the last-mentioned cap to be moved longitudinally withrelation to the nozzle carried by the first-mentioned cap and withrelation to each other.

2. In an ejector, a casing having a removable cap on one end providedwith an integral nozzle, a removable cap on the other end of the casingprovided with a depending wall, an adjustable ejecting-tube mounted inthe depending wall, an adjustable nozzle mounted in the cap, and meansto lock the nozzle in its adjusted position.

, In testimony whereof I affix my signature in presence of twowitnesses.

WILLIAM D. LABADIE.
